I know there is a couple of similar questions but all of them seem to have trouble with NVIDIA graphics. However, I have a built-in Intel graphics.
Whenever I try to open system settings, the system logs me out. After re-login, all the applications I had open are closed (i.e. this is really log-out, not just locking the screen).
Solutions I have tried
- NVIDIA drivers issues: as I said, I don't use an NVIDIA graphics card
.Xauthorityfolder: I don't have this folder
This is a desktop PC with ASRock Z390 Extreme 4 motherboard. The only external hardware connected is an external WiFi adapter.
sudo inxi -SCG:

I also tried to run
gnome-control-center &> before-log-out.log and this is the contents of the file I have after having logged back in:
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0" after 11 requests (11 known processed) with 0 events remaining.
If I log in with Wayland, I can open settings without any problem. The output of
inxi -SCG is the same with the only difference:
However, on Wayland the system is much slower (even the mouse movements are noticeably irregular). This issue is posted as a separate question.
